Hello,

Export of temporary buffers with babel src blocks fails.

Line 118 of ob-exp.el has

(set-buffer (get-file-buffer org-current-export-file))

But the value of org-current-exp-file is nil for a temporary buffer.

The following commit brought in that change.

    ob-exp: resolving code block parameters in the original file on export

    * lisp/ob-exp.el (org-babel-exp-src-blocks): now switching back to the
      original file before resolving code block parameters to ensure
      headline and buffer wide parameters are taken into consideration
      when only a narrowed portion of the file is exported


HTH,

Puneeth
